Answer:
f(-2) = 5
Step-by-step explanation:
We just need to substitute x with -2 and simplify.
f(x) = 2x² - 3
f(-2) = 2(-2)² - 3
f(-2) = 2(4) - 3
f(-2) = 8 - 3
Best of Luck!

Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
y=5x+3y=5x+3

27
643-166=477
477÷18=26.5
Then, round to the nearest whole.
Which makes it 27 sets.
a = 2
Multiply equation by 2a to get rid of denominators.
10 + a = 12
